Novice A/Advanced A: Squares
If we have a square $$$s$$$, and another square $$$S$$$ which completely covers $$$s$$$,
then the intersection of $$$s$$$ and $$$S$$$ is a valid square.
Recall that we can pick any valid square, so long as the coordinates for both axes are in the range $$$[-10^9, 10^9]$$$.
Note that all coordinates for our squares are in the range $$$[-10^9, 10^9]$$$.
Also, consider that we are allowed to print any square that satisfies
the condition in the problem statement.
Consider Hint 1: if another square completely covers one square,
then their intersection remains a square. Thus, the easiest construction is for our square $$$S$$$ to cover all the input squares completely.
Because of this, we can print a square with its lower-left corner at
$$$(-10^9, -10^9)$$$ and its upper-right corner at $$$(10^9, 10^9)$$$.
inf = 10**9
print(-inf, -inf, inf, inf)
